A long-term fix for a broken intersection

The conversation around the work at the intersection of Route 118 and Underhill Avenue often centers on timing — why it takes as long as it does, and why it can’t move faster.

But focusing only on speed misses the larger point. This project is not a surface repair. It is a structural correction and modernization of an intersection that was never built to handle today’s traffic patterns or tomorrow’s demands.

At its core, this is about capacity and flow. The widening of the roadway to introduce dedicated turning lanes is not cosmetic—it is operational. Without defined turn lanes, through-traffic is routinely forced to slow or stop behind turning vehicles, creating backups, inefficiencies and safety risks. By separating those movements, the intersection functions as it should: more predictable, more efficient and safer.

And this isn’t theoretical — it’s proven. Across New York and nationally, intersection widening that incorporates dedicated turn lanes has consistently demonstrated measurable improvements: reduced vehicle delay, shorter queue lengths and fewer rear-end and angle collisions. Transportation studies routinely show that even the addition of a single turning lane can significantly increase intersection capacity and improve level of service, particularly at peak hours. In practical terms, that means less time sitting in traffic and a safer, more orderly flow for drivers, pedestrians and emergency vehicles alike.

Equally important is the reconstruction of curbing — much of which was outdated, deteriorated or missing altogether. Curbing is not just a visual edge; it defines lanes, channels stormwater, protects pedestrians and supports the integrity of the roadway itself. Rebuilding it correctly is part of establishing a complete and durable streetscape.

Then there is the signal system. The shift from a wire-hung traffic light to a mast arm (telescoping arm) system is a deliberate infrastructure upgrade. Wire systems, while common in older corridors, limit flexibility. Any future widening, alignment adjustment or utility work often requires tearing into the roadway again to reposition poles and spans. A mast arm system, by contrast, provides both durability and adaptability — allowing future improvements to be made with minimal disruption.

This is what thoughtful infrastructure looks like: not just fixing what’s broken, but building in a way that anticipates what comes next.

All of this work is being executed to the standards of the New York State Department of Transportation, ensuring that the intersection meets modern design, safety and performance criteria. Those standards require precision, sequencing and inspection. They are not compatible with a rushed timeline.

There is always pressure to move faster, especially when work impacts daily life. But the tradeoff is real. Move too quickly, and you risk doing the job twice. Take the time to do it correctly — with proper lane configuration, curbing, drainage and signal infrastructure — and you create a roadway that works not just today, but for years to come.

The inconvenience is temporary. The improvement is permanent. With a projected completion targeted for Memorial Day weekend, the goal is clear: deliver a finished product that meets the highest standards and is ready for the demands of the summer season and beyond.
